Touchi Extract

Also known as: Touchi, Touchi extract (TE), fermented soybean extract, Touchi Extract

Overview

Touchi extract is derived from fermented soybeans and is recognized for its alpha-glucosidase inhibitory activity, making it an important supplement in managing blood glucose levels. Traditionally used in Chinese cuisine, this extract has gained popularity for its antihyperglycemic effects, particularly among individuals with borderline and type 2 diabetes mellitus. Research on Touchi is at a moderate maturity level, supported by several clinical trials demonstrating its efficacy in reducing postprandial and fasting blood glucose levels, alongside HbA1c. The extract can be delivered in powdered forms, commonly taken before meals to enhance its effects on carbohydrate digestion.

Benefits

Touchi extract provides several significant benefits, primarily through its ability to lower postprandial blood glucose and HbA1c levels. In clinical studies, participants experienced notable reductions in HbA1c levels, from 10.24% to 8.96%, and fasting blood glucose levels decreased from 6.9 mmol/L to 6.4 mmol/L over several months. Additionally, it has been shown to moderately lower serum lipids and total cholesterol, while increasing HDL levels. These effects are particularly beneficial for individuals with borderline and type 2 diabetes, who can expect to see results within 2-3 months of consistent use. The strength of evidence for these benefits is reinforced by well-designed randomized controlled trials (RCTs) with clear outcomes and safety data.

How it works

Touchi extract functions primarily as an alpha-glucosidase inhibitor, blocking the enzyme responsible for breaking down carbohydrates in the intestine. This inhibition slows down carbohydrate absorption, thus effectively lowering postprandial blood glucose levels. By impacting the gastrointestinal system, Touchi extract enhances glucose metabolism and improves overall glycemic control. The mechanism is straightforward: by delaying the digestion of carbohydrates, it reduces spikes in blood sugar that typically occur after meals.

Side effects

Touchi extract is generally considered safe with long-term use, and studies indicate no common side effects reported. Adverse effects have been rare, with no significant abdominal discomfort or gastrointestinal disturbances noted in clinical trials. Although <5% of participants may report minor symptoms, they remain non-threatening. Importantly, while there are no documented drug interactions, those using other diabetes medications are advised to consult a healthcare provider prior to use. Special populations, such as pregnant or breastfeeding women, should also seek medical advice. Caution is warranted in individuals with pre-existing severe gastrointestinal conditions.

Dosage

The recommended dosage for Touchi extract is between 0.3 g to 1 g per meal, totaling 0.9 g to 3 g per day, depending on individual needs. For optimal results, it is suggested to take it before meals to maximize its alpha-glucosidase inhibiting effects. Clinical trials have safely employed doses up to 3 g per day for twelve weeks, indicating its efficacy at this upper limit. The extract is usually consumed in a powdered form, which is well-absorbed when taken prior to carbohydrate intake. No specific cofactors are needed for absorption.
